  • Modeling and Simulation of Sulfur Hexafluoride (SF

    Sulfur hexafluoride (sf 6) was first prepared by H. Mossian in 1902 and commercial production of gaz sf6 was initiated by Allied-Signal Inc., U.S.A., in 1948. The basic properties of gaz sf6 at 25 oC and 1 atm are summarized in Table 1 [Marshall, 1976; Takaiki, 1976; Grant, 1995]. sf 6 is a colorless, odorless and tasteless gas
